GRAIN*- DRILL.

SPECIFICATION forming part of Lettersvlatent No. 458,371, dated August25, 1891.,

Application tiled June 12, 1891. Serial No. 395,999. (No model.)

T0 all whom t may concern:

Be it known that I, DANIEL E. MCSHERRY, a citizen of the United States,residing at Dayton, in the county of Montgomery and State of Ohio, haveinvented certain new and useful Improvements in Grain-Drills, of whichthe following is a specification, reference being had therein to theaccompanying drawings, in which- Figure l represents a perspective viewof one of myimproved grain shoes or hoes complete; Fig. 2, a verticalsectional view showing the pivotal connection between the wheel orroller and the rear side of the seed boot or spout, and Fig. 3 a detailperspective view of the casting swivelly connecting the wheel to thehoe.

This invention has special relation to graindrills wherein eachshoe-runner and hoe carries a spring-depressed pivotally-connectedpressure or covering wheel that follows' along in the furrow behind theshoe and serves to yieldingly press the soil down upon and cover theseed dropped in4 the furrow, each wheel operating independently1 ofevery other and being free to rise and fall and swing laterally as theexigencies of the case may require; and it has for its objects,particularly, the provision of simple and eectual means for making aswiveling connectionof the covering-wheels to the rear sides of the seedspouts or boots of each shoe, so that each wheel will be free to riseand fall independently of the others, and also swing laterally toreadily follow the furrow, as will be more fully hereinafter described.

In the drawings annexed, c designates the seed-spout of an ordinary oranyimproved grain hoe or shoe, and as this forms no part of my presentinvention I do not deem it necessary to further refer to it in thisspecification.

Riveted or formed integral with the seedspout, on its rear side near itsupper end, is a pair of separated rearwardly-proj ectin glu gs or ears bZ), between which is pivoted bya vertical bolt c a laterally-swingingcasting d, said vertical pivotalboltpassing downthrough holes in theears and the intermediate casting and provided with a nut on its lowerend. Clamped between the upper end of the casting and the upper ear isthe lower horizontal portion of an upwardly extending angular arm e, theupper end or portion e of which is bent horizontally rearwardly. Formedintegrally with the swinging casting is a horizontal tube or sleeve d',this sleeve extending across its rear side or edge and having'a passagethrough it for the horizontal pivotal bolt f. The bolt f pivotallyclamps the forward ends of the arms g of the presser-wheel g to theopposite ends of the transverse sleeve d', the presser-wheel beingjournaled between the rear ends of the arms. At a suitable point betweenthe wheel and the pivotal head is rigidly clamped between the arms, andby means of a horizontal bolt h', a short bar or plate 71., the boltpassing entirely through it and the arms. Pivoted on the bolt h', in anopening in the plate h, is the lower end of a fiat vertical bar 7e, theupper end of which works freely in a slot in the horizontal p01'- tion eof the angular arm. A coiled expansible spring is placed upon the rod Itbetween the arm e and the block h, to keep the wheel yieldingly presseddownwardly.

It will be observed thatV by this construction of the connecting devicesthe presserwheels will be free to swing both vertically and laterallyand at the same time be kept pressed constantly downward, no matter inwhat position the wheels may be in respect to the hoe. The verticalmovement is ativantageous in that it permits the wheels to yieldindependently of each other in riding over obstructions and undulationsin the soil, and the laterally-swinging movement is obviously importantin that it permits the wheels to freely follow the furrows whether theybe curved or straight. The pivoted arm e is an important feature in thatit is free to swing around with the wheel and keep it constantly presseddownwardly. This connection is eX- tremely simple and effectual, andwill not be liable to readily get out of order.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is-

l. The combination of a grain-drill shoe, a casting or block pivoted onthe rear side of the same by a vertical bolt, a transverse sleevecarried by the casting, wheel-carrying arms IOC pivoted to thistransverse sleeve, and means for-.depressing the wheel, substantially asdescribed.

2. 'The combination of a grain-drill shoe provlded with ears on its rearside, a casting piyoted between these ears byavertical bolt, thiscasting having formed integral-with it across its rear side a horizontaltube or sleeve, and arms pivoted to the ends of this sleeve byahorizontal bolt, Said arms carrying a Wheel at then` rear ends,substantially as described.

3. Thev combination of a grain-drill shoe, a laterally-swinging castingpivoted thereto by a Vertical bolt, a horizontal bolt pivoted to therear side thereof, and vertically-swinging arms pivoted on said bolt,said arms carry- 1ngapresser-wheel,substantiallyasdescribed.
